vrf to/from socket

Question asked by VRFuser on Dec 4, 2003


Hi Scott et al.,

Thanks for the reply.  I kind of thought this might be the case with the
to/from socket thing.  I do have it working with the UDP sockets in VEE 6.0
but with the ActiveX calls to MSWinsock.  We were thinking of testing
communications via TCP anyway since UDP doesn't have error checking.  If
anyone is interested in seeing how I did it with ActiveX/UDP let me know and
I'll send you a copy of my code (it's really small and simple).
Best,
Karen

Hi Karen and vrf,

As far as I know, VEE cannot handle UDP sockets, only TCP. I think you're
going to need to use TCP as the base protocol in order for VEE to
participate.
